Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cloudflare

  • Free tier limited to basic features (no advanced analytics or premium features)
  • Pro tier ($20-25/month) caps at professional websites (higher tiers needed for enterprise scale)
  • Caches only anonymous API GET responses (authenticated requests and non-GET methods not cached)
  • Geographic coverage limited to announced 330+ cities (may not cover all regions globally)

Splunk

  • No prices are published on any plan; every model requires contacting sales for an estimate
  • Three separate pricing models, workload, ingest and entity, so the same deployment costs different amounts depending on which was signed
  • Ingest pricing bills on data volume, so cost tracks how much you log rather than how much value you get from it
  • Security, observability and platform are priced separately
